Abstract (English):
The article describes the problem of the electric station power control. Currently, the most data on the supervisory control and controllability of electrical equipment comes from the remote control systems. The prerequisite for constructing the new electric power facilities or for the reconstructing the old ones is the introduction of the remote control systems. The remote control systems are rapidly developing and improving. Initially, all of them consisted of a controlled terminal that monitors and controls the system by receiving and processing analogue signals coming from analogue measuring transducers via numerous direct cable communication lines. The main disadvantages of such systems of remote control include a large number of connecting cables, scaling difficulties and low metrological characteristics. With the advent of digital transmitters, it became possible to transmit the digital signals, which reduced the number of connecting lines, simplified scaling and increased the reliability of technical systems. Today, using one measuring transducer makes possible to measure several parameters at once. The main measured parameters of power plants include the intensity of a current, phase voltages, AC frequency, active, reactive and total power. There has been described the arrangement of the remote control and communication systems of the Astrakhan TPP-2. The algorithm for monitoring the power of the station has been analyzed. A variant of its modification is proposed. An example of introducing the proposed modification of the algorithm is described. The practical significance of the study includes reducing costs caused by deviations from the station’s active power values set by the dispatcher, which are cured by LUKOIL-Astrakhanenergo, LLC.
